3 Claims.

'This invention relates to an improved window frame assembly.

An object is to provide a window frame assem bly ofa unitary structurewhich is adapted to fit within window openings which may vary slightlyin size, without the usual cutting and fitting of parts which is nowrequired to mount a window frame within a window opening and the windowsash within the frame;

The assembly comprises a window frame provided with the usual slidablewindow sash and jamb guides therefor, and also a screen and mountingtherefor, and means associated with the frame assembly, and forming apart thereof adjustable to enable the frame assembly to fit withinprovided window openings which vary somewhat in size.

Window frame assemblies of this character may be fabricated entirelywithin the factory and shipped as unitary structures and stored as Vsuch until they are required for use. They may be mounted on the job byordinary labor, and do not require the skilled labor necessary to fitwood sash and wood frames as they are conventionally fitted today.

The construction shown is a composite structure, being formed in part ofwood and in part of metal, but the major portion of the structure isformed of shaped metal strips fitted together to define a window frameexhibiting jamb channel guide portions, a header portion, a sillportion, and adjustable jamb header and sill strips which are carried bythe frame assembly but adjustable relative thereto, and adapted to besecured to the frame of the window opening to mount the frame assemblytherein.

A meritorious feature is that the construction 2 tures will more fullyappear from the following description, claims, and accompanyingdrawings, wherein:

Figure 1 is an inside elevation of a window opening in a buildingprovided with my improved assembly.

Figure 2 is an enlarged broken vertical sectional view taken on thesection line 2-2 of Figure 1.

Figure 3 is a broken horizontal sectional view taken on the section line3-3 of Figure 1.

Figure 4 is an enlarged fragmentary vertical sectional view through thelower sash portion of the frame assembly.

Figure 5 is an enlarged fragmentary horizontal sectional view showing amodified form. of screen sup-port.

Heretofore in the mounting of a window frame within a window opening,and in the mounting of window sash within the frame, it has been commonpractice'for a carpenter to fit each frame to its opening. The framesare of standard size, and the openings are so formed, but the frames donot fit the openings closely enoughto make a good joint, and fitting onthe job has been necessary. Unless the window sashes were mounted withinthe frame in the factory, it was necessary that they also be fitted onthe job. This is painstaking, accurate work which it is diflicult isbuilt up of simple, inexpensive, easily assembled metal strips sofastened together as to make a unitary frame assembly and so providedwith adjustable sealer strips as to be capable of being mounted andfitted within a window opening and forming a tight seal therewith.

In the preferred construction shown, the assembly includes upper andlower sliding sash mounted within the window frame for raising andlowering. These sliding sashes are formed of metal and a metal framescreen is associated therewith and adapted to be interposed across thespace normally closed by either sliding sash. The frame assembly is soconstructed that either sliding sash may be removed for glazing or thelike without disassembling the other portion of the frame.

Other objects, advantages,and meritorious feato obtain under presentconditions, and it is costly to accomplish. Metal window frameassemblies have heretofore been provided, but upon mounting the same ina window opening it was necessary to fill in around the metal frame tomake it fit the window opening. The construction of this application issuch that adjustable parts are provided which are readily shiftable toadapt the frame assembly to fit window opening; which vary somewhat insize, and to form a close joint and seal therewith.

The window opening within which my improved assembly is to be mounted isshown in a building having an outer brick wall, and is defined by aheader portion ID, a sill portion 12, and

opposed jamb portions [4. These window openings though designed to acertain dimension will made up of a header portion [8, a sill portion20, and a pair of opposed jamb portions 22, all secured together to forma substantially rectangular frame with the ends of the jamb portionsprojecting at the bottom as shown in Figures 2 and 4. To each of thejamb portions 22 there is secured a metal jamb guide member having apart 24, which over-laps the inner face of the jamb portion 22, and issecured by screws 26 thereto. ,This guide member is shaped to provide apart 29. which over-hangs the outer face of the jamb portion 22, and todefine a pair of sash guide channels 28, as shown in Figures 3 and 4.

Each of these guide members 24 is made in two parts, namely, an upperportion for the upper sash, and a lower portion for the lower sash,which facilitates independent removal of the sashes. The portion 29 ofthis member which over-hangs the outer face of the wood jamb '22,

is spaced therefrom so as to provide a recess therebetween, extendinglongitudinally of the jamb portion, and. within which a jamb sealerstrip 30 is slidably received. A pair of these jamb sealer strips aremounted within this recess, as shown in Figure 1. They over-lap at theirmeeting ends so as to provide for adjustment longitudinally within therecess. They are slidably adjustable laterally in and out of the recessto bring the outer flange 32 of each strip into engagement with the jambportion i i of the window opening.

It will be seen that when this window frame assembly is mounted within awindow opening, these jamb sealer strips may be slidably adjusted to bebrought into contact with the jamb portions Id of the opening and screws34 may be passed therethrough and into the inner stop It to position andsupport the window frame assembly within the opening. Thesescrews areshown particularly in Figures 3 and 5. They are there shown as extendingbetween the wood jarnb portions 22, and the flanges 32, but the screwsmay cut through the wood jamb member if desired.

Upper and lower window sash 36 and 38 are provided. These are slidablysupported within the guide channels 28, hereinabove described. Thesesashes are here shown as metal sashes provided with glass panes.Comparable metal sashes. are shown in my pending United Statesapplication for patent, Number 592,340, filed May '7, 1945, now Patent2,525,322, granted October 10, 1950. Thetop rail of the lower sash isprovided with a screen supporting ledge. 40, and the bottom rail of thelower sash is shown as provided with a screen retaining ledge 42,hereinafter more specifically described. This invention concerns theframe assembly and its mounting within the window opening and not thedetails of the sash structure.

- There is a header element which has a part 44, that is secured byscrews or the like 46 to the wood header [8. This header element is bentupwardly to over-lie the outer face of the wood header I8, and to form adownwardly open channelportion 48 which over-hangs the guide channels 28of the jamb guides and receives the upper rails of the sliding sashes.upon the'wood header I8 is a header element 50. This header element isof channel formation and is received over the header element 18, asshown inFigure 2. This element 50. is adapted to be secured by nails 52or the like to the header portion of the window opening. It is providedwithan outwardly projecting weather protective Slidably mounted lip 54adapted to rest upon the top of the channel portion 48 heretoforedescribed, and as shown in Figure 2.

There is a sill member which has a part 56 that extends over the innerface of the wood sill 20 and may be secured thereto by nails 58. Thissill member is bent as at 60 to over-lap the outer face of the wood sill20 and is spaced therefrom to provide a recess therebetween. This sillmember is also shaped to provide a shoulder portion 62 whichextends'across and underneath the sash guide channels 28. The portion 62is "then bent downwardly as at 64, as shown in Figures 2 and 4.

There is a sill sealer strip 66 which is slidably received underneaththe margin of the part 64 and between the part 60 and .the wood sill 20,so as to be snugly supported, and is slidable up and down to have itsweather protective lip portion as brought into engagement with the sillportion l2 of the window opening. Screws 10 may be used to fasten thissealer strip in place.

It will be seen that each of the sealer strips, namely, the sill sealerstrip, the header sealer strip, and the two jamb sealer strips are eachslidably associated with the window frame assembly. Each is adapted tobe secured to a part of the window opening to position the frameassembly therein. They also hold the frame assembly therein. The lowerprojected ends of the wood jamb portions 22 are cut off to the properlength, so that when the wood header portion is is received within thechannel of the header element 50, as shown in Figure 2, such lower endswill rest upon the sill portion 12 of the window opening.

It is recognized, however, that the seal formed at top and bottombetween the window assembly and the window opening, is formed by theheader element 5!] and the sill sealer strip 66, respectively. It isalso understood that the jam-b sealer strips 30 are not only adjustablein and out laterally, but are adjustable linearly of the window opening,so as to provide an effective seal.

The sil1 of the window frame assembly is also provided with a member 72which may be secured thereto by nails T4 and which has a part 16 that isbent to slope outwardly and downwardly, as shown in Figures 2 and 4.This sloping part is adapted to retain a screen such as is shown inFigure 4, and indicated by the numeral 78 in place. In such figure ametal screen is shown as resting at the bottom upon the sill member 56,of the frame, and as having its upper margin received underneath thedownwardly and outwardly extendingscreen retainer flange 42 of theupraised lower sash. An angle strip 80 is also secured to the wood jambportions 22 by the screws 26. This strip has a face portion 82, shown inFigures 3 and 5, against which the screen 18 is adapted to rest when itis disposed underneath an elevated sash, as shown in Fig 1. A windowframeassembly. adapted to be received within the margin of a windowopening 7 comprising, in combination, a rectangular window framestructure including a rectangular wood frame made up of a pair of jambportions, a header portion, and a sill portion, a sash guide membersecured to each wood jamb portion and having a part defining a pair ofparallel sash guide channels offset laterally of the wood jamb portion,a channel guide for a screen telescoped over the back of one sash guidechannel and having one leg disposed between the two adjacent side wallsof the two sash guide channels, said screen guide having a width greaterthan the width of the sash guide channel telescoped thereby andproviding a third parallel channel disposed laterally beyond the twosash guide channels and providing a guide channel for a screen.
